Audio Analogue AIRTECH Upgrade Kit for AA100DM

The Audio Analogue AIRTECH Upgrade Kit for the AA100DM is a connection set that lets you link two AA100DM amplifiers into a bridged mono pair.

The AA100DM is the Class AB stereo amplifier of the Pure AA line with 100 watts at 8 ohms per channel. Bridged, each unit becomes a mono amplifier with 400 watts at 8 ohms. The kit provides the necessary connection plus a quick-start guide for this – it doesn't swap any components and doesn't turn a single amplifier into a different device.

Why the AIRTECH Kit?

Because more power doesn't necessarily mean a new device. If you already own an AA100DM and notice your speakers want more, you place a second one next to it and run both bridged in mono. 100 watts per channel becomes 400 watts at 8 ohms – and your system stays in the same sonic family, instead of you starting over from scratch.

What you get

A connection set for bridged mono operation of two AA100DM units, with the manufacturer's accompanying quick-start guide. Audio Analogue doesn't publish a fully itemized scope of delivery – we confirm it with the distributor before you order, rather than guessing here.

Who is the kit for – and who isn't it for?

Straight talk: the kit is intended exclusively for the AA100DM, other amplifiers are out of scope. With just one AA100DM in the rack it's useless to you, because bridged mono needs two units. And if 100 watts at 8 ohms has never run out on you in your room, skip it: the more honest lever in that case is speakers, not a second amplifier.

Our verdict

An unfussy, clean way up for AA100DM owners – provided the second amplifier is already on the cards anyway. Whether bridged mono really achieves anything with your speakers, we'll work out honestly with you beforehand instead of just selling you hardware: HD Zürisee in Wädenswil, 044 680 22 00.

Frequently Asked Questions

What does the AIRTECH Kit do for the AA100DM?

It links two AA100DM amplifiers into a bridged mono pair. Each amplifier then only powers one channel and delivers 400 watts at 8 ohms instead of 100 watts. According to the manufacturer's manual, the kit contains the necessary connection plus a quick-start guide and is obtained together with the second AA100DM.

Do I need two AA100DM units for this?

Yes. Bridged mono means each amplifier takes on exactly one channel – so for stereo you need two AA100DM units plus the kit. The mode can't be used with a single unit. Whether this step achieves anything with your speakers, we'll look at together beforehand.

Does the kit replace components inside my amplifier?

No. It's a connection set for bridged operation, not a component upgrade. The electronics inside your AA100DM stay unchanged, nothing gets swapped and nothing gets re-soldered. If you're hoping for a sonic rebuild of the single device, this isn't it: the effect comes solely from bridging two amplifiers into mono.

Does the kit also fit other Audio Analogue amplifiers?

No, the manufacturer specifies it explicitly for the AA100DM. Other models in the Pure AA and Anniversary lines handle mono operation differently. If you're not sure which amplifier is sitting in your rack, send us a photo of the back panel – we'll tell you what fits.

Why buy the AIRTECH Kit from HD Zürisee?

Because bridged mono needs to be wired cleanly and configured correctly – wired wrong, the amplifier can suffer in the worst case. Our own technician takes care of that, and we confirm scope of delivery and availability with the distributor beforehand. Questions? 044 680 22 00 or WhatsApp 076 534 22 00 (text only, no calls).
